An opening or recess 56 is formed in display stand 50 for permitting the portion of the alarming power cord 42 to be extended and retracted from the reel 44 within the hollow interior of the display stand 50. When a potential purchaser picks up the item of merchandise M, reel 44 rotates on hub 54 and torsion spring 52 is wound (i.e. tightened) as the alarming power cord 42 is unwound from the reel. As a result, reel 44 is biased by the wound torsion spring 52 to automatically retract the portion of the power alarming cord onto the reel as the potential purchaser returns the item of merchandise M to the display stand 50. As shown, the strain relief block 46 may optionally comprise one or more magnets 48 for engaging corresponding magnets 58 provided on the display stand 50 to position the item of merchandise M in a desired orientation on the display stand 50.

The merchandise security system 40 further comprises a power cable 60 that extends between a power source, such as a power strip, terminal or the like, that is electrically connected to a conventional 110 Volt Alternating Current (AC) power outlet. Alternatively, the power cable 60 may be directly connected to the power outlet. Regardless, the power cable 60 is electrically coupled to an electrical circuit, for example a printed circuit board (PCB), 62 disposed within the hollow interior of the display stand 50. As shown, PCB 62 may have electrical leads 64 that terminate in electrical terminals 66 configured to engage and electrically couple with electrical traces 67 formed on the interior surface of a door 51 of the display stand 50. Door 51 is adapted to be opened to receive reel 44 within the hollow interior of the display stand 50 and to be closed to retain the reel within the interior of the display stand. Electrical traces 67 are configured to electrically couple with corresponding electrical traces 47 provided on an exterior surface of reel 44. In turn, the electrical traces 47 of the reel 44 electrically couple with the electrical conductors disposed within the alarming power cord 42. As such, the power cable 60 is operable to provide electrical power to the item of merchandise M. As illustrated, the electrical traces 67 may be circular in configuration to facilitate electrical communication as the reel 44 rotates.

As previously described, the power cable 60 provides an electrical signal, including a power signal, to the alarming power cord 42 for charging and/or powering the electronic item of merchandise M via the electrical connector 43 and the power input port P of the item of merchandise. The merchandise security system 40 comprises monitoring electronics on the PCB 62 that monitor the electrical signal in the power cable 60 and the alarming power cord 42 to determine whether the electrical signal has been interrupted, for example, by disconnecting the alarming power cord from the power input port P of the item of merchandise M, or by electrically decoupling the alarming power cord 42 from the power cable 60 at the electrical traces 47, 67 of the rotatable reel 44 and the display stand 50, respectively, by opening the door 51, or by cutting/severing the alarming power cord 42 or the power cable 60 at any point between the power source and the item of merchandise M. In the event that the electrical signal is interrupted, PCB 62 may activate an audible and/or a visible alarm to alert store personnel to a potential theft of the electronic item of merchandise M, as previously described.

It is important to note that the merchandise security system 40 comprises an alarming power cord 42 that extends continuously from the power input port P of the electronic item of merchandise M to an electrical coupling (e.g. electrical traces 47, 67) disposed adjacent the central socket 45 of the rotatable reel 44 and the hub 54 of the display stand 50. Accordingly, the alarming power cord 42 does not comprise a first cable configured for electrical connection to a second cable selected from a plurality of adapter cables to provide an appropriate operating voltage and/or current to the electronic item of merchandise M. Furthermore, the alarming power cord 42 is not in direct wire-to-wire electrical communication with the power cable 60 since the alarming power cord and the power cable are separated by PCB 62, electrical leads 64, electrical terminals 66 and electrical traces 67, 47. In addition, the merchandise security system 40 of the present invention further comprises a strain relief block 46 for preventing the electrical connector 43 at the free end of the alarming power cord 42 from being removed, disconnected or dislodged from the power input port P of the electronic item of merchandise M.
